Letters Patent No. 104,891, dated June 28, 1870..

IMI ROVEMENT IN HORSE HAY-FORKS.

The Schedule :eIerred to in these Letters Patent and making part of th sa To all whom it may concern:

Be it known that I, GEORGE W. S mon, of Shippensburg, county of Cumberland and State of Pennsylvania, have invented a new and useful Improvement in Hay-Elevators; and.I do hereby declarethat the.

following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, wherein- Eigure 1 represents the invention with the .points closed.

Figure 2 represents the same with the points open.

Figure .3, a plan of the trip-lever.

The nature of this invention consists in the construction and arrangement of the several parts, as will be hereafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct the several parts of the elevator of steel or iron, or both metals, A being the stem; B, the spear; C, the grapple; D, the trip-lm'er; which constitute the several pieces.

Thesteni A has at its upper end an eye, (I, to which is fastened the elevating-cord a.

At its lower end it is furnished with aws, which straddle the grapple 0, and to which it is pivotedby a bolt, a working freely in it.

The spear B at its upper end is turned at right angles, and has an eye at b, through which the stem A is inserted and slides freely upon it.

The lower end of the spear is made tapering to enter the pile of hay, and is curved inwardly.

Through B, at (l and D are mortises for the reception of the trip-lever D and grapple 0, both of 'which are pivoted freely on bolts.

Grapple Ois turned at its upper end at rightangles, and at its lower end bent in an elliptical curve, so that, when in action to raise the weight, the point,c crosses the point 11 several inches, as represented in The grapple is so pivoted on the lower end of the stem A that, when the catch of the trip-lever is released, it will hang in the position shown in fig. 2

scribed.

much more thanit will readily open to discharge the hay, when the load is an additional force to open the grapple.

- It is also pivoted through the. spear B at 11*, so that, when the load is to be discharged, the spear drops down from the first position in fig. 1,.and takes the sloping direct-ion in fig. 2, to aid the rapid discharge of the load.

The trip lever D, as shown in fig. 3,'is bent at right angles, and rebent, as at ll, to act as a cat-ch for the upper end 0' of .the grapple O.

It is pivoted to the spear B at (I and is curved out wardly toward its handle, where it has an eye, (I, for fastening the trip-cord ll", which cord may be led -oii in any suitable direction, or it may be passed through an eye upon the convex side of the grapple, which would insure the release of the load by forcing the grapple and the trip-lever together.

1n the first position, fig. 1, the elevator is represented as closed upon its load. The spear is strongly braced by the eye b being firmly set against the eyering at a. The trip-lever D is firmly holding the upper end of the grapple by its catch (1, thus holding the grapple against its load ot'hay, while the stem A is the connecting-link supporting the entire load at its point and no possible release can cccurnntil the catch at d is lifted from c, which is readily effected by pulling down the cord (1, when instantly the weight will throw outward the grapple into position sccoud in fig. '2, and the load will be discharged.

Having clearly explained,the operation of my invention,

That I claim as new therein, and wish to secure by Letters Patent of the United'States, is'-- The combination and arrangement of the stem A, the spear B, the grapple O, and the trip-lever D, all constructed substantially as and for the purposede- GEORGE W. SHADE.
